Was also there Saturday and I don't know if recent reports just had us going in with super low expectations, but I was actually pleasantly surprised with our park experience other than the high temps, which we of course knew about (still so tiring, however). Don't get me wrong, I still miss Maxpass. A lot. And Saturday was definitely crowded. (You know it's busy when Pooh and Ariel are both listed at 30 minutes.) But we found nearly all rides had a shorter wait time than was posted (which I hadn't experienced in my other visits since the park reopened though others had reported experiencing that.) The only exception was Soarin' (45 min), which was also the one attraction along with Haunted Mansion where we were just drained and miserable due to the waiting outside in the heat. (That "hidden" back area where the Soarin line loops around is just terrible.)
We did single rider for RSR and Space Mountain (both 15 min) and Guardians twice, once regular and then Monsters After Dark. The two waits were listed as 65 and 95 and we waited 25 and 40, respectively. (Not saying 40 is ideal, but it was prime evening time. and definitely better than 95.) All in all, we arrived at 9, left at 10 and managed RSR, TSMM, Guardians 2x, Ariel, Animation Academy, Incredicoaster, Pooh, ROTR, Haunted Mansion, Lincoln, Space Mountain, Indiana Jones, Pirates, fireworks, breakfast from the Shawarma cart (love all that seating nearby), two mini Avengers shows, lunch at Hungry Bear and dinner at Cocina Cucamonga. Far from our best day as far as how much we did, but a pretty full one still.
We upgraded our tickets to keys and got a reservation for the following morning so popped in for breakfast, Pooh and a few Fantasyland rides before heading to an appt. in Orange County. (Due to the appt., we had a hotel room overnight.)
We only had two rides that were "musts" for us this visit—Guardians After Dark and Haunted Mansion—so figured anything beyond that was extra. We mostly went to try the pumpkin cheesecake funnel cake at Hungry Bear
And while not OC-local, we're close enough at 45 min away to know we have the luxury of coming back soon. It's definitely a reminder that experiences on a single day can vary wildly.
